Abstract
An archive of an object set may include various security features that enable a detection of alterations of the contents of the objects. However, the security measures of an archive may fail to detect an inadvertent or intentional alteration of the structure of the object set, including the addition of new objects, changes to the metadata (e.g., the name, position within the object set, and location and size within the archive) of respective objects of the object set, and the deletion of directory entries for the objects. Therefore, an archive may be generated with verifiers (e.g., hashcodes) calculated not only for the contents of objects, but for the directory of the archive, and may be included in the signature of the archive. This verification may extend the detecting of alteration of the archive to include the structure of the archive as well as the contents of the objects contained therein.
